LIABILITY; EXCULPATION; INDEMNIFICATION

11.1 Liability. Except as otherwise provided by the Delaware Act, the debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and no Member or Manager shall be obligated personally for any such debt, obligation or liability of the Company solely by reason of being a Member or Manager.

	a.		No Covered Person shall be liable to the Company or any other Covered Person for any loss, damage or claim incurred by reason of any act or omission performed or omitted by such Covered Person in good faith on behalf of the Company and in a manner reasonably believed to be within the scope of authority conferred on such Covered Person by this Agreement, except that a Covered Person shall be liable for any such loss, damage or claim incurred by reason of such Covered Person’s gross negligence or willful misconduct.
	b.		A Covered Person shall be fully protected in relying in good faith upon the records of the Company and upon such information, opinions, reports or statements presented to the Company by any Person as to matters the Covered Person reasonably believes are within such other Person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the Company, including information, opinions, reports or statements as to the value and amount of the assets, liabilities, Profits, Losses or Net Cash Flow or any other facts pertinent to the existence and amount of assets from which distributions to Members might properly be paid.

11.3 Fiduciary Duty. To the extent that, at law or in equity, a Covered Person has duties (including fiduciary duties) and liabilities relating to such duties to the Company or to any other Covered Person, a Covered Person acting under this Agreement shall not be liable to the Company or to any Member for its good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict the duties and liabilities of a Covered Person otherwise existing at law or in equity, are agreed by the parties to replace such other duties and liabilities of such Covered Person.

11.4 Indemnification. To the fullest extent permitted by applicable law, a Covered Person shall be entitled to indemnification from the Company for any loss, damage or claim incurred by such Covered Person by reason of any act or omission performed or omitted by such Covered Person in good faith on behalf of the Company and in a manner reasonably believed to be within the scope of authority conferred on such Covered Person by this Agreement, except that no Covered Person shall be entitled to be indemnified in respect of any loss, damage or claim incurred by such Covered Person by reason of gross negligence or willful misconduct with respect to such acts or omissions; provided, however, that any indemnity under this Section 11.4 shall be provided out of and to the extent of Company assets only, and no Covered Person shall have any personal liability with respect to such indemnity.

11.5 Expenses. To the fullest extent permitted by applicable law, expenses (including legal

fees) incurred by a Covered Person in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Company prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Company of an undertaking by or on behalf of the Covered Person to repay such amount if it shall be determined that the Covered Person is not entitled to be indemnified as authorized in Section 11.4.

11.6 Insurance. The Company may (but is not required to) purchase and maintain insurance, to the extent and in such amounts as the Board shall, in its sole discretion, deem reasonable, on behalf of Covered Persons and such other Persons as the Board shall determine, against any liability that may be asserted against or expenses that may be incurred by any such Person in connection with the activities of the Company or such indemnities, regardless of whether the Company would have the power to indemnify such Person against such liability under the provisions of this Agreement. The Company may enter into indemnity contracts with Covered Persons and such other Persons as the Board shall determine and adopt written procedures pursuant to which arrangements are made for the advancement of expenses and the funding of obligations under Section 11.5 and containing such other procedures regarding indemnification as are appropriate.

11.7 Outside Businesses. Any Member or Affiliate of a Member may engage in or possess an interest in other business ventures of any nature or description, independently or with others, similar or dissimilar to the business of the Company, and the Company and the Members shall have no rights by virtue of this Agreement in and to such independent ventures or the income or profits derived from such ventures, and the pursuit of any such venture, even if competitive with the business of the Company, shall not be deemed wrongful or improper. No Member or Affiliate of a Member shall be obligated to present any particular investment opportunity to the Company even if such opportunity is of a character that, if presented to the Company, could be taken by the Company, and any Member or Affiliate of a Member shall have the right to take for its own account (individually or as a partner or fiduciary) or to recommend to others any such particular investment opportunity.
